The 1930 24 Hours of Le Mans was the 8th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 21 and 22 June 1930. It saw the first appearance of a German car and the first entry from female drivers.[1]
In the smallest ever field in the Le Mans history; there were only 17 starters. This was a race of two halves. At the start the Mercedes of Rudolf Caracciola/Christian Werner was pursued by the supercharged ‘Blower’ Bentley of Tim Birkin. Twice he passed the white car on the Mulsanne Straight and both times he was thwarted by a rear-tyre blowout. Then Sammy Davis chased in a works Bentley. When that car was put into the sandbank at Pontlieue corner, it was the other works Bentley of Woolf Barnato and Glen Kidston taking up the Germans’ challenge. The lead changed a number of times into the night, until at 1.30am when the Mercedes was retired with a broken dynamo and a flat battery.[1]
After that it became a procession for the remaining Bentleys, although both the privateer Blower Bentleys retired on Sunday.[1] The two works cars carried on and cruised to another formation finish. Barnato had won his third consecutive Le Mans, from three starts. Talbot finished third and fourth and took the lucrative Index of Performance prize by the narrowest of margins (0.004) from the winning Bentley. The Bugatti of Marguerite Mareuse and Odette Siko had a trouble-free run and finished seventh, stealing the contemporary headlines from Bentley.[2]
Regulations
The AIACR (forerunner of the FIA) Appendix C rules stayed in effect. The biggest change this year was the Automobile Club de l'Ouest (ACO) now allowing private entrants as well as “works” entries from the manufacturers. This just acknowledged the existing practice of private owners being entered by the car-company. Five engine-classes were specified, with brackets at 3.0, 2.0, 1.5 and 1-litres.
To be eligible, a minimum of thirty vehicles had to have been produced, and the cars had to be “as per sales catalogue”. Many small companies were selling bare chassis upon which an owner would get a coach-builder to put on a body-shelled, so the specifications were still quite broad as long as the car had some basic minimum equipment (mudguards, lights, hood, windscreen etc.).[3]
As engine power advanced, the ACO once again adjusted the Index target distances. Example targets included the following:[3]

The Société des Pétroles Jupiter, Shell's French agents, provided three standard fuel options: Gasoline, Benzole and a 70/30 blend of the two. Teams were allowed to add up to 2% by volume of their own additives. As before, all liquids (fuel, oil and water) could only be replenished after every 20 laps (326.8km (203.1mi)).[3]
Night-time, when headlights had to be used, was defined by the ACO for the race as between 9.30pm and 4am.[3]
Entries
In the middle of the Great Depression, the auto-industry was being hit very hard. Only 33 cars entered for the race, of which only 19 arrived. That said it was a quality field with two big Bentley entries challenged by a mighty 7-litre supercharged Mercedes and one of the supercharged Alfa Romeos dominating European racing, both privately entered. France could muster only two works Tractas, a BNC and a privateer Bugatti to their premier touring car race.[4]

Defending champions Bentley once again arrived with a solid works team, this year bringing a trio of their big Speed Six model. Introduced in 1928 as a competitor to the Rolls-Royce Phantom I, it had a 6.6-litre engine that produced 190bhp giving it a top speed of 185kp/h (115mph). Company director (and race winner in 1928 and 1929), Woolf Barnato would drive the lead car – the same chassis that had been entered in the 1929 race. This year his co-driver was his wealthy friend Glen Kidston. The other two were driven by 1924-winner Frank Clement with former Stutz-driver Dick Watney, and 1927-winner and journalist Sammy Davis with Clive Dunfee.[5]
Back in 1928, Barnato's fellow race-winner, SirHenry “Tim” Birkin had seen the threat posed by the new supercharged Mercedes and Alfa Romeos to Bentley's dominance of touring car racing. He had approached W. O. Bentley and Barnato about supercharging the green cars. Barnato was not convinced and W.O loathed the idea.[6] He eventually found an investor in the form of young heiress, and keen motorist, Dorothy Paget (who already owned a Mercedes-Benz SSK). The cars were not race-ready in time for the 1929 race; however Barnato quietly approved sufficient funds to allow the required production quantity to be met. Based on the 4½ Litre model, a massive, distinctive Roots supercharger was fitted in front of the radiator. This boosted the engine output from 130 to 240bhp. However, it also raised the fuel consumption and its front-end weight gave the car noticeable understeer. Improved over the close-season, a team of three “Blower Bentleys” arrived, managed by former Bentley-driver and Lagonda team-manager Bertie Kensington-Moir.[6] Birkin renewed his 1928 Le Mans partnership with Jean Chassagne, while race-winner Dudley Benjafield drove with former Alfa Romeo test-driver (and now British resident) Giulio Ramponi. The third car was driven by Boris Harcourt-Wood and Jack Dunfee, Clive's older brother.[7]
Blower Bentley
The first German car to run at Le Mans was a privateer entry. Mercedes and Benz had merged in 1926 and had considerable racing success, but with the Depression the company closed its works racing team. Team manager Alfred Neubauer, however, convinced the board to bankroll a privateer team. This was run by their top works driver Rudolf “Rudi” Caracciola. The SSK (Super Sports Kurz) was designed by Ferdinand Porsche as a development of the SS model. The giant 170bhp 7.1-litre engine could be augmented by a Roots supercharger to put out 300bhp.[8] However, unlike the Bentleys, the supercharger was not designed to be run all the time (not least for reasons of chronic fuel consumption), and the team was able to convince the ACO to discount the 1.3 supercharger modifier when dictating the car's target distance.[8] Caracciola's co-driver was also from the Mercedes-Benz works team, Christian Werner.
Mercedes SSK
Stutz was present at Le Mans again, through two black-painted private entries. The latest model M versions came in two wheelbase lengths, with the shorter designated the “MA”. The new 5.3-litre sidevalve engine now put out 120bhp. Edouard Brisson was having his first race after the bad 1929 Le Mans when a fuel-fire had badly burnt his face and hands. His co-driver was the experienced Louis Rigal, former Ariés works driver. The other car was owned by wine-company heir Philippe de Rothschild. Keen to keep his anonymity he raced under the pseudonym “Georges Philippe” and had an American banking friend, Dick Parke, put the entry in for him. He had Edmond Bourlier (formerly from Talbot and Delage works teams) as his co-driver with Parke acting as reserve driver for both cars.[9]
The Sunbeam-Talbot-Darracq marque returned to Le Mans this year. The successful Talbot 14/45 had been developed into the 18/70 model with a racing version, the AO90 (a reference to its top speed over 90mph[10]). The 2.3L engine now put out 95bhp. The Fox & Nicholl team were looking for new cars since Lagonda closed its racing programme in January. They purchased three Talbots but a disastrous fatal accident at Brooklands wrecked them. In less than five weeks, two were repaired for Le Mans. Georges Roesch, chief engineer at Clément-Talbot, was concerned that like the Blower Bentleys, the French fuels would not be suitable for the Talbots. He asked the ACO if they could run on ethyl fuel but this was refused. Leslie Callingham, head of Shell's technical department in London (and driving an Alfa Romeo in the race) said the hybrid fuel would be suitable, although the engine output would drop to about 70bhp. The drivers were to be Johnny Hindmarsh / Tim Rose-Richards and Brian Lewis, Baron Essendon / Hugh Eaton.[10]
The other significant Le Mans debut was also a privateer entry. Alfa Romeo had already achieved great success in grand prix racing in the 1920s. Vittorio Jano’s 6C successor design, debuting in 1927, followed on this adapting as a sports car or grand prix racer in the Formula Libre events. Initially a 1.5-litre, in 1929 it was also available with a 1752cc twin-cam engine, and both versions had a supercharged variant. As well as a works team, two other new significant customer teams ran the 1750 SS: Enzo Ferrari in Italy and Fred Stiles, the London importer, focusing almost exclusively on their respective countries. Its light weight and superior handling gave it excellent acceleration and made it better through the corners than the bigger cars. Le Mans was not considered by any of the three teams. However, a car owned by wealthy British racer Earl Francis Howe was entered, with support from the Stiles team including former Bentley driver, Leslie Callingham as co-driver. With the 1.3 supercharger co-efficient they had the same Index target as the Talbots.[11]
Alfa Romeo 6C-1750 SS
After the withdrawals of Alvis and the new Scotsman car, the only entries in the 2-litre class were from BNC and Kenneth Peacock's supercharged Lea-Francis S-Type. Having raced the year before, Peacock had purchased a new car and returned as a privateer entry with Sammy Newsome again as co-driver.[12]BNC had not survived the economic downturn and had been purchased by French entrepreneur Charles de Ricou, who also picked up Lombard and Rolland-Pilain, and its successor AER. The BNC Vedette was the new model based on the F28, the last Rolland-Pilain design.[13]
Bugatti, despite having organised races for its car-owners on the Le Mans circuit, had not competed in the endurance race since the inaugural 1923 race. Wealthy French heiress Marguerite Mareuse entered her Type 40 tourer as a privateer, inviting talented driver Odette Siko as her co-driver – becoming the first women to enter the race. Based around the 1.5-litre engine of the Type 37 race-car, it put out about 45bhp to a 4-speed gearbox.[14]
Mmes Mareuse & Siko with their Bugatti in the pits
Jean-Albert Grégoire’s small Tracta company had been very successful at Le Mans with its reliable front-wheel drive and patented Universal joint system. The works team bought two Type A models to the race (unsupercharged this time), Grégoire racing with Vallon as usual, and Bourcier with Debeugny.[15] The smallest cars in the field were from MG Cars, making its Le Mans debut. Morris Garages was set up in 1909 by William Morris as a sales/service division of his Morris Motors. In 1928 after strong sales success, the company was relaunched as MG Car Company under Cecil Kimber. The MG M-type “Midget” was built on the Minor chassis with a plywood and fabric body. This year's version had the 847cc engine uprated to put out 27bhp that made it capable of 110kp/h (70mph). Two cars were prepared for Sir Francis Samuelson and Huskinson & Fane, the London MG agents.[16]

Practice
On race-week, the competitors were allowed to do practice laps on the Wednesday, Thursday and Friday nights between 10pm and 6am. However, the roads were not closed to the public and the ACO advised drivers it was at their own risk.[3] The big Mercedes showed its class, able to reach 195kp/h (120mph) on the Mulsanne straight.[17]
The Paget-team Bentleys had a bad practice week.[18] The Harcourt-Wood/Dunfee car had a big-end failure and all the cars were suffering overheating issues. This was found to be due to the high combustion temperatures of the hybrid fuel. The team decided to switch to the pure-benzol option, but it meant changing the engine compression ratios and fitting new pistons. There was only time to change two of the cars so the Harcourt-Wood/Dunfee car was withdrawn.[19][20] Faced with a similar issue, the Talbots had been modified in May.[10]
The BNC team had a last minute emergency just before the start. A split fuel-tank needed to be emptied and repaired. The race started as it was being refuelled, but then the car refused to start.[13][21] So the starting field was only 17 – the smallest in the Le Mans race history.[4]>
Race
Start
As a change from recent years, the race-day was sunny and hot.[4] Caracciola, at the head of the line, was away first. On lap 2, his first flying lap, he broke the lap record (with a 6m52s) and then turned off the supercharger. This allowed the hard-charging Birkin in his Blower Bentley to close in. W.O. Bentley preferred to let the privateer do the chasing, telling his drivers to look after their cars and wave him through.[22][19] On the fourth lap, Birkin was on Caracciola's tail at the Pontlieue curves. Reaching 195kp/h he got past the Mercedes as they braked heavily for the Mulsanne corner. Birkin did a 6m48s to set a new lap record, but on the next lap the tread came off a rear tyre and he had to pit. It took only half a minute to change the wheel, and then in only five laps Birkin was right behind the Mercedes. Just as he again overtook Caracciola on the Mulsanne Straight the tread on the other tyre let go. Although he dropped two wheels off the road, Birkin was able to complete the pass until the tyre blew at Arnage forcing him to pit yet again.[4][18]
Race start – Brisson's Stutz ahead of Birkin
Meanwhile, further back, de Rothschild had gone into the tight Arnage corner too fast and ploughed into the earth bank at speed. Able to reverse back out, he made it to pits where the crew verified the damage was not severe.[21] The other Stutz had also had problems, with Brisson handling a misfiring engine at the start and then Rigal running off the road a couple of times, dislodging the exhaust pipe. The Lea-Francis lost time when it came to a stop about a kilometre from the pits. It took half an hour, but once Peacock cleaned the spark-plugs he was away again without further bother.[21][12]
Caracciola's next challenger was Sammy Davis in his works Bentley. Despite a stone thrown up and smashing his goggles he stayed on the German's tail to the first pitstops after 20 laps. Bloodied, he handed over to Clive Dunfee who only managed a half-lap when he buried it in a sandbank at Pontlieue. With no shovel on hand it took him, and then Davis, over two hours to dig it out only to discover the front axle was wrecked.[22][21] Kidston pitted his Bentley with a tyre tread thrown on his in-lap. Barnato took over and set about gradually closing in, finally overtaking Werner in the Mercedes around 8.30pm.[17][6]
Behind the Mercedes and Bentleys ran the Stutzes and the Earl Howe's Alfa Romeo. The Talbots were running 9th and 10th, but were able to run an hour longer than the bigger cars ahead of them before refuelling.[23] They picked up a place as the Alfa Romeo was delayed – a race-long struggle with fouled plugs and ignition from the blended fuel.[11] At the back of the field, the nimble MGs were easily leading the Tractas (delayed, like others, by plug issues[15]) in their own battle for small-engine honours.[21] However the MGs soon ran into trouble. Samuelson's was waylaid by a failed big-end bearing, while Murton-Neale's skated off the track at the Pontlieue corners. French gendarmes had just sprinkled sand over the road to stop melting tar in the afternoon heat. He was furious and angrily threw the fencing he had just demolished with his car at the officials.[24] Back at the pits, the car got assessed from damage. His co-driver did a few laps but was not convinced it was safe, so Murton-Neale got back in and drove on into the night. Around half-time, the car was finally retired with a broken con-rod.[16]
Barnato cornering at Pontlieue
At 9pm the Brisson/Rigal Stutz caught fire suddenly on the Mulsanne Straight. The improvised repairs to the exhaust pipe had come loose and flames set the car alight.[9][25] Rigal managed to pull the car over and get out, narrowly missed by Barnato's Bentley. Hindmarsh, also running close behind him, stopped his Talbot and ran to help him with his own fire extinguisher.[23] Parked far from any marshal posts, it took an hour for the fire to be put out, as official cars ferried fire extinguishers to the incident. The flames dazzled drivers[25] and smoke from the destroyed car could be seen from the middle of Le Mans city. Not long after, the other Stutz had retired. The rear axle had, in fact, been knocked in de Rothschild's excursion and broke, leaving him not far from the other smouldering Stutz.[9]
Night
By nightfall, after five tyre failures, the Birkin/Chassagne car was running seventh. In the sister car, Ramponi pitted with a high fever and feeling quite unwell. Benjafield took over facing having to drive the rest of the race.[19] Mercedes team manager Neubauer authorised his driver to start re-using the supercharger to close back in and going into the night, the spectators watched a thrilling duel as the two cars swapped the lead.[25] Just before midnight the two pitted together and the Bentley just got out first. This came to an end at 1.30am though when the Mercedes slowed with its headlights flickering. Werner pitted but could not restart from its pitstop.[17] A wire had come loose on its dynamo and the battery had gone flat. This left the Bentleys running 1-2-3-5, the works Speed Sixes ahead of the Blowers with Barnato/Kidston holding a six-lap lead over Clement/Watney.[26] The Talbots were now running fourth and sixth, splitting the hard-charging Birkin/Chassagne Bentley making up for its lost time. Shortly before 3am, Rose-Richards bought his Talbot into the pits when the front-wing began to come apart, affecting his headlamps. The team jury-rigged a fix with wire and cords.[23] This allowed the Alfa Romeo, running better in the cool night, to pass back into sixth.[27]
Morning
The second half of the race devolved into a routine procession. Early morning mist and a heavy rain shower also contributed to a dour race. After 8 o’clock Birkin and Chassagne finally caught the Lewis/Eaton Talbot and moved up to fourth.[23] But then just before midday their Bentley broke a conrod and had to retire. Then within an hour, the other Blower Bentley also lost its engine, after Benjafield had driven solidly for fourteen hours without relief.[19] This promoted the Talbots now into third and fourth, until the running repairs on the Hindmarsh/Rose-Richards car came adrift again. This time they pulled off the superfluous headlamp and secured the fender with leather straps going around the radiator cap and front chassis. The three pitstops required again allowed Howe's Alfa to get past a second time.[23]
In the early afternoon, a short, heavy downpour swept across the circuit.[24][3] The main excitement was the close race for the Index prize between Bentley and Talbot. Both teams told their leading cars to push on harder. With two hours to go, Eaton pitted his Talbot to clear a fuel blockage: a paper label off a fuel-churn had fallen in and got stuck on the filter. It cost a lap and let the Bentley get ahead. The handicapping favoured the smaller car and Eaton's hard driving soon retook the lead only to lose it again when they pitted to free a stuck throttle. When a late stop delayed Howe in the Alfa Romeo, the Talbots once again were in third and fourth.[23][27]
Finish and post-race
Once again Bentley staged a formation finish. Woolf Barnato, getting back-to-back victories in the same Speed-Six chassis as he driven to win in 1929, promptly announced his retirement with the enviable Le Mans record of three entries for three outright wins. In the end the Alfa Romeo was only eighteen kilometres (1 lap) behind the Talbots. British drivers filled the first six places with the privateer Lea-Francis coming home in sixth. Despite the early delay, Peacock and Newsome still covered four more laps than their previous year's effort.[12]
Barnato & Kidston in their winning Bentley Speed Six
In a tight finish, Talbot won the Index prize by the narrowest of margins: only 0.004 from the winning Bentley, amounting to barely a lap between them. Three French cars were the remaining finishers, highlighted by the women in the Bugatti after a trouble-free run to seventh, and Jean-Albert Grégoire leading home both his Tracta cars.[26] Grégoire was lucky to finish, as he had just put his car in a ditch on his last lap. Unofficial help from spectators pulled him out in time.[1]
It was a curious fact that the Bentleys had a number of tyre delaminations of their Dunlops. Whereas the Talbots, and Mercedes (albeit abbreviated), had run on their starting set of Dunlops through their whole race.[20]
Bentley had now achieved five wins in the first eight Le Mans. But like many other manufacturers, the company was hit hard with plummeting demand in the Great Depression and soon after Bentley disbanded its works racing team. In 1931 Barnato let two loan repayments lapse. The receivers were called in and in November the company was bought out by Rolls-Royce.[22][1] Nor did Glen Kidston get back to Le Mans. A keen pilot, he was attempting an endurance record from England to Cape Town when he was killed on the return route when his plane broke up pin stormy weather.[22]
In October, Dorothy Paget withdrew her financial support for the Blower Bentley project after ongoing unreliability and only limited success.[19]Philippe de Rothschild, knowing his identity was now revealed, retired from racing to build his family company into one of the great French wine labels.[9]

Finishers
Results taken from Quentin Spurring's book, officially licensed by the ACO[28] Class Winners are in Bold text.
Sir Henry Ralph Stanley Birkin, 3rd Baronet, known as Tim Birkin, was a British racing driver, one of the "Bentley Boys" of the 1920s.
The 1936 Grand Prix season was the third year of the 750 kg Formula. The next iteration of the Mercedes-Benz did not prove successful and the team withdrew during the season to instead prepare for the next one. It therefore fell to the resurgent Auto Union team to dominate the racing. In particular, it was their young, new superstar, Bernd Rosemeyer, who mastered the tricky car and who showed superlative skill in wet conditions. Rosemeyer easily won this season's European Championship by winning three of the four Grands Prix.
The 1972 24 Hours of Le Mans was a motor race staged at the Circuit de la Sarthe, Le Mans, France on 10 and 11 June 1972. It was the 40th running of the 24 Hours of Le Mans and the ninth race of the 1972 World Championship for Makes.
The 1968 24 Hours of Le Mans was the 36th Grand Prix of Endurance, and took place on 28 and 29 September 1968 on the Circuit de la Sarthe, in Le Mans, France.
The 1937 24 Hours of Le Mans was the 14th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 19 and 20 June 1937. The race was won by Jean-Pierre Wimille and Robert Benoist in Roger Labric's works-supported Bugatti team, in one of the streamlined new Type 57G cars, at a record pace and exceeding 2000 miles in the race for the first time.
The 1935 24 Hours of Le Mans was the 13th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 15 and 16 June 1935. The race was won by Johnny Hindmarsh and Luis Fontés in a British Lagonda, breaking the run of four consecutive Alfa Romeo victories. A record number of 58 starters included a record number of British cars, at 37, dominating the smaller classes. Another notable point of the entry was four all-female cars, and a Le Mans record of ten women competing.
The 1934 24 Hours of Le Mans was the 12th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 16 and 17 June 1934. Four privateer Alfa Romeo entries were expected to fight for outright honours, with an outside chance for the four Bugattis ranged against them. British cars dominated the smaller classes. Two-time winner Raymond Sommer soon took the lead until, after only 90 minutes, he stopped out on the circuit with smoke pouring from his engine. For the next five hours the Alfas of Luigi Chinetti and Earl Howe duelled for the lead. However, soon after night fell, the lights failed on Howe's Alfa costing him two hours to get the electrics repaired. Chinetti took the lead, but their car had developed a leak in the fuel tank. The solution was the same as Sommer had used the previous year: to plug the gap with chewing-gum.
The 1933 24 Hours of Le Mans was the 11th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 17 and 18 June 1933. Up against five strong privateer entries from Alfa Romeo, the opposition looked fairly weak, mostly being of 1920s vintage. There was a strong British contingent in the smaller classes. The big drawcard was the presence of top European drivers Louis Chiron and Tazio Nuvolari. The current European champion was paired with one of the previous year's winners, Raymond Sommer
The 1932 24 Hours of Le Mans was the 10th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 18 and 19 June 1932. A significant year for the Automobile Club de l'Ouest (ACO) with the biggest changes to the circuit in the race's history. A new section bypassing Pontlieue suburb was built starting with a long right turn after the pits, going over a hill then down to the Esses, a left-right combination, before rejoining the Hunaudières straight at the new right-hand corner of Tertre Rouge. This shortened the track by almost 3 km down to 13.491 km (8.383 mi).
The 1931 24 Hours of Le Mans was the 9th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 13 and 14 June 1931.
The 1929 24 Hours of Le Mans was the 7th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 15 and 16 June 1929.
The 1928 24 Hours of Le Mans was the 6th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 16 and 17 June 1928.
The 1925 24 Hours of Le Mans was the 3rd Grand Prix of Endurance, and took place on 20 and 21 June 1925. It was the last of the three races spanning 1923 to 1925 to determine the winner of the Rudge-Whitworth Triennial Cup, as well the second race of the inaugural Biennial Cup.
The 1935 Grand Prix season was the second year of the new 750 kg Formula. The success of the previous year encouraged the AIACR to reinitiate the European Championship. It was composed of the seven national Grands Prix and was won by Rudolf Caracciola, driving for the Mercedes-Benz team. The team dominated the season winning five of those Grand Épreuves, as well as four of the other major races of the season. However, in one of the great motor-races in sporting history, Tazio Nuvolari in a Scuderia Ferrari Alfa Romeo beat the combined numbers of the German teams in their home Grand Prix. The season also saw the arrival on the international stage of the bright young talent Bernd Rosemeyer in the Auto Union team.
The 1931 Grand Prix season was a watershed year, with the advent of the AIACR European Championship. After several years of Grand Prix racing in the doldrums with little technical development, 1931 saw new models come from all three main manufacturers: Bugatti, Maserati and Alfa Romeo.
The 1932 Grand Prix season marked the second year of the AIACR European Championship. It saw the debut of Alfa Romeo's sensational new Tipo B and with it, Tazio Nuvolari won the Championship driving for the Alfa Corse works team. The 40-year old Nuvolari won two of the three rounds and was second in the other. Still running to a Formula Libre rules for the cars, the regulations were revised to set the races to be between five and ten hours. However, all three national committees ran their races to the minimum time-limit.
The 1934 Grand Prix season saw the advent of the new 750 kg Formula. In an effort to curb the danger of rising speeds, the AIACR imposed this upper weight limit that effectively outlawed the large capacity engines. The incumbent manufacturers Alfa Romeo, Maserati and Bugatti had been preparing their new models with varying success – the best of which was the Alfa Romeo Tipo B. However, it was the state-sponsored arrival of the two German teams, Mercedes-Benz and Auto Union, and their innovative and progressive cars that ignited a new, exciting era of motor racing.
The 1930 Grand Prix season continued the malaise that had taken over the sport. Although there was little technical advance more privateer teams were forming, getting some factory support. The AIACR continued to mandate its fuel-regulated Formula Libre rules. Across the Atlantic, the AAA abandoned the AIACR regulations. Their new regulations were derisively called the “Junk Formula” by purists, opening up to their own version of Formula Libre: with modified stock-standard cars of up to 366 cu in (6-litres) with two seats.
Bentley Blower No.1 is a racing car developed from the Bentley 4½ Litre by Sir Henry "Tim" Birkin to win the Le Mans twenty-four-hour race. The car was developed into its current form for racing at Brooklands.
Colonel Reginald Clive Gallop was an engineer, racing driver and First World War pilot. He was one of the team which developed their first engine for Bentley Motors.
